Synopsis
The club members leave their own starsand trails for Hitomi to combine the magic. As there is still a little time left before the moon completely matures, each member decides to leave her their own personal messages: Yamabuki wishes for her to have more confidence in herself, Chigusa wishes for her to smile more, Kurumi thanks her for joining the club, Asagi promises to write her letters dated to the future, Kohaku gives her her love, and Aoi wishes her all the best in the future and promises never to forget her. Hitomi also announces about how much she has changed since coming here and thanking them for all these irreplaceable feelings and memories. In the midst of her announcement though, Hitomi's magic interferes, breaking the time magic. Aoi jumps into the magic circle to save her but they return to Hitomi's room of monochromatic drawings. The two finally confess their feelings after realizing that they had always been similar in shutting themselves up away from their own emotions, and embrace each other. For them who had both brought color into the other's future, Hitomi regains her sense of colors and they are successfully transported back to the present. Hitomi is returned to the future just as everyone wishes her goodbye, but only Kohaku knows that the time magic she cast didn't do the trick, instead Hitomi's own unconscious erasure of colors from her vision was the limit that had broken the time magic Kohaku's future self cast.

Back in 2078, an old Kohaku gives Hitomi a time capsule everyone made using their photography skills, but she is especially touched by a picture book called "The Seven-Colored Penguin" that was the only book she read in color as a child, revealed to be written by Aoi himself and detailing the change of a monochromatic penguin (Hitomi) to a colorful one with the help of a rabbit (Asagi), a flying squirrel (Kurumi), a bear (Aoi), a dog (Yamabuki), a cat (Chigusa), and a parrot (Kohaku). Hitomi, having regained the people and emotions she lost as a child, returns to her life with renewed vigour and joy.
